Nope.
The prime BTL areas in the North are back to 2000ish prices, taking away the doubling in prices loads of IO BTL piling in caused.
The rents just about cover mortgage costs. Theres problems with voids or, worse, non paying tenants that need a court order n bailiffs to quit.
And we've not seen a large scale exiting of IOBTL yet. That'll happen as the tax Bill's arrive.

Bricks are a compromise.
I remember reading a book about a bloke having a barn rebuilt as a house in the 1930s. One chapter was a discussion about getting brickies rather than stone masons- plently more brickies, being loads cheaper/less skilled, and walls are built faster.
I'd guess the operating costs of the robot are massive - break downs, setup costs etc etc.
Besides, these are large concrete blocks rather than small bricks.
And its Oz.

Because until ~2002ish none of the banks got into IO BTL lending.
Previously, LL mortgages were low LTV and handled as commercial loans.
No past lending means they have no idea of how the loan perform over the business cycle.
Then, rather than being cautious and stepping back and thinking thru what could go wrong, all the banks,. a large number who were building societies less than 10 years earlier, started down the massive lunacy of high LTV IO BTL.
They are insane and they deserve to bust.
My local building society - and it was still a BS when it went under - had lent over £1m in IO BTL to someone who, when they bothered to luck after the loans had all gone bad, was on DLA.

US saving rates are shooting high as people are panicking.
High saving rates is a negative for house buying.
In a typical uk recession only a small number of take a hit on jobs andor earnings - say 5%-10%, most of whom get another job within 6 months. So about 10% reduction in entire earnings.
News was reporting that 75% are reporting incomes are down 25% or more.
That's a much larger reduction, all in.
And a lot of the jobs are not coming back.
House stock is still in a bubble. Incomes have not caught up with housing costs.

For 30-50% OAPs there tends to be a very expensive stay in a care home.
Besides, the probate sale is one more house on the market.
My local area is now at the stage where probates sale exceed mortgage able buyers.
And then youve got to include the nuts LA bludnering ahead wit htheir local plan of buildign another 1000 houses.
